Abstract:
The RPL specification allows nodes running with storing or non-
storing modes to operate in the same network. We describe how such a
mix can result in network partitioning even when there are plenty of
physical links available in the network. The partitioning affects
both upwards (nodes to root) and downwards (root to leaf) traffic.
This routing pathology stems from a recommendation made in the RPL
specification forcing nodes with different modes of operation to join
the RPL network as leaf nodes only. We propose a solution that
modifies RPL by mandating that all the nodes parse and interpret
source routing headers and storing mode nodes to sometimes act like a
non-storing mode root by attaching source routing headers.
